I get them too when even trying to use the function tracer in some
simple way.  They occur in random places and eventually the entire
machine wedges and is unusuable.

I suspect there is some bug that ends up corrupting memory, so I
started trying to debug this last night when I first saw it.

I'll let you know if I make any progress.
